Can't Connect To A Specific Network
Dec 20, 2012
After not using my computer for a week due to illness I've turned it on to discover that it cannot connect to the wifi network that has been working fine for the last few months. The network is shared and I don't personally have access to the router, and the network administrator is away at the moment so I can only attempt solutions at my end.It seems it might be an IP configuration issue. Network diagnostics gave me the error message "Wireless Network Connection 4 doesn't have a valid IP configuration", as well as one or two other IP-themed error messages.
My computer thinks it's connected. It says I'm connected to the network and that I have internet access, but there's no actual connectivity.Finally, weirdly, I did seem to manage to connect briefly at one point. It took about three minutes to load the Google homepage and then dropped again. I have no idea what the significance if any of that is.I know the following for sure:
- the wifi network does work; I'm using it on my laptop right now
- the network adapter on my computer also works, it can connect to the wifi hotspot on my phone

Using my current network, I am unable to connect to [URL].It doesn't matter what browser I use or if I use a cli-command (wget, curl).
Error in Google Chrome:
Oops! Google Chrome could not connect to [URL]
Error using curl:
curl: (7) couldn't connect to host
If I use nslookup to get the IP-address of YouTube, I get 173.194.32.32.If I go to http://173.194.32.32/ in my browser it can connect, but as Google is probably checking the Host HTTP-header, it shows Google's frontpage instead.
There is no blocked websites on the router and other devices on the network seems to work.My computer only has this problem on this specific network.
I am using Mac OS X 10.8.2 on a MacBook (mid 2009).

I was trying to configure a friend's router, but their laptop wouldn't connect wirelessly. Initially, I couldn't connect via ethernet cable either, but I went into the settings and set it to obtain an IP address automatically. After that, I could connect via ethernet no problem.I was able to successfully connect wirelessly on two different mobile phones.I still can't connect wirelessly to this router (well, technically it says it's connected to the network, but it won't connect to the internet, nor can I bring up the hub settings). However, I can connect to their old router no problem. I'm not sure whether the problem lies with the laptop or the router, and don't presently have another laptop to check

I provide support for a small business network. ISP: Silo Wireless (wireless point to point with ISP) Router: Cisco RV220W Wireless-N Network Security Firewall
The router is configured with two wireless access points with SSIDs: "abracadabra" and "abracadabra-guest". The only difference between these two wireless networks is their passcode. Up until now I have had no problem connecting devices to either wireless network.
My problem lies with an HP Pavilion laptop running Windows Vista Home Premium 32-bit that I'm trying to connect to the "abracadabra" wireless network.
Network and Sharing Center shows "Identifying" for a while and then shows "Unidentified network" with no local or internet access. Wireless network connection status says that Media State is Enabled, Speed is 54Mbps and Signal Quality is Excellent. Network Connection Details shows that DHCP is Enabled but it's getting an Autoconfiguration IPv4 address of 169.254.107.138...
The laptop is running ESET Nod 32 Antivirus 5 and Windows Firewall and I've disabled Windows Firewall on the Wireless Network Connection. I've also tried re-installing the wireless nic driver, it's running the latest from Windows Updates.
what really gets me is that the laptop can connect to "abracadabra-guest" fine and access the internet

I'm using a coaxial networking system and would like to electronically identify each section of coax in my network with a mac id for tracking purposes. Is there any way to do this without taking much space? Is there a microchip that I can install,preferably something that can withstand extreme environments?

Is it possible to enable an absolute value rate limit using QOS on a HP ProCurve 5406 switch for a particular IP range on a specific port? Is there a way to configure our HP 5406 with an absolute rate limit on "WAN" port for that server's IP range? I would like to limit it to only being capable of sending 1Mbps worth of traffic over the head end at once.Everything in the documentation points towards priority queues, which as far as I can tell, isn't really what I want.Baring accomplishing this goal using rate limiting is there a better way to prevent our services from accidentally saturating this connection?i thimkong about somthing like that:
class ipv4 rate-limit-port-A1
match ip 10.136.0.0/16 any
exit
policy qos port-a1-ratelimit
class servers-to-be-slowed action rate-limit kbps 1000
exit
interface A1 service-policy port-a1-ratelimit inI'm not sure about this.

I use a router RV082 with load balancing. My problem is when I try to access a specific site, I get the error message that my IP address changes and I can not use 2 ip address. I want to specify an ip range to always use the same WAN port.

ASA 5520 running 8.0.4
ASDM v.6.1
Need assistance understanding how in ASDM/Configuration/Site-to-Site VPN/Connection Profiles/ "Any Entry" I can specify that I only want to offer an IKE Proposal of pre-share-aes-256-sha?
The IKE Proposal field has a number of possible options including: pre-share-aes-256-md5, pre-share-3des-md5, pre-share-aes-256-sha, pre-share-aes-192-sha, pre-share-3des-md5, pre-share-aes-sha and pre-share-3des-sha.
I am able to pick a specific IPSec Proposal w/o issue but when I attempt to do the same for the IKE Proposal, and click OK the choice does not "stick" but rather returns to the entire list as defined above.

I am unable to connect to facebook with any reliability. It will go to the site every once in a while but I would say a very small success rate.
I don't have this problem with any other website and my hosts file hasn't blocked facebook.
Also when I enter the url and press enter, it goes to a google search with a very long url, this doesn't happen with any other url.

I was trying to enter Minecraft but none of my browser could connect. If I connected through hidemy***.com it would load normally. When I try to join any server through the game, it gives me an error. If I change to my other network it doesn't connect, but I can if I use another OS or computer

I don't think this is specifically an internet explorer problem but i could not figure out which category it could have gone in. A few months ago random websites started becoming completely inaccessible to my internet connection, no matter how often i would try. The most recent one to have happened allowed me to connect just yesterday, but today i cannot connect to the website from this connection. I was able to connect to the website when i used the computer at a friend's house.

I have two webites hosted by the same company. Yesterday I thought their server was down. To make a long story short, everyone I talk to can access the sites and I cant my hosting company says its a router problem. I contacted the service provider and reset the router but that didnt fix it. I have 3 computers on this router and none of them work to access the site. I reset the ip config, I've tryed EI and Firefox. I checked the IE diagnostic log but dont know what it means and it says:
0" ?>
<?xml-stylesheet type='text/xsl' href="xpnetdiag.xsl" ?>
<xpnetdiag>

I'm trying to solve up a really nasty problem I have at home and I've come here hoping to find some answers. Since last Saturday, I am unable to access certain internet sites when at home. Strangely enough everything was fine before that. Went to bed around midnight local time and when I went to check those sites after work at around 3:30 pm local time I could not get on those sites. For some reason the pages just keep on endlessly loading, giving me only a blank page. What is also strange is that no computer in my house can access those sites. So it's not limited to one computer.

I have multiple Windows XP and Windows 7 machines. All of the XP machines are unable to connect to a specific website URL and all the 7 machines connect just fine. All machines are on the same network.I have tried firewalls on, off, and uninstalled. I am the network designer and we have no proxy, blocks or routes for blocking.Have downgraded from IE 8 to IE 6 and also installed other browsers such as Firefox and Chrome and those do not work either.

My USB wireless adapter does not detect one specific network anymore on my laptop (toshiba). It was detecting it until a while ago, and all of a sudden I cannot see the network anymore. However, when i connect the wireless adapter to my other laptop (lenovo), the network is detected. Nothing has changed in the wireless network, and no programs were installed on my laptop (toshiba) before the network stopped appearing.

I'm just new with ASA. I'm just self-studying on it. I was tasked to have an ACL that will allow inside hosts to access a specific network. Is there a way on how to know all the inside hosts on the behind ASA so that I can do a "object-group network" on those inside hosts which I think it will look neat.

my laptop, which connects fine to all other wireless networks, has trouble on this one. It can browse the web all day, but the second a large file begins to transfer (video, a file download, etc.) it will drop the connection randomly, usually rather quickly. The computer does not need to be restarted to reconnect, it often reconnects on its own near-immediately, though sometimes I have to go to the system tray and reconnect manually.I thought it was too far from the router, but my tower in the same room connects flawlessly, and going in to the same room as the router doesn't work. This same laptop has been fine on every other network, and every other computer is fine on this network. I've web crawled off and on about this for months, but no one's problem is limited to one computer/network combination.

As you can see at the picture below i have 2 routers connected via two fastethernet links. Both routers running BGP. R1 (AS 65100) and R2 (AS65000).
R1 got a loopback interface with the IP address 1.1.1.1 255.255.255.255 R2 got two loopback interfaces 2.2.2.2 255.255.255.255 and 3.3.3.3 255.255.255.255.
Let's say that i want the host 3.3.3.3 to go over fa0/1 to reach 1.1.1.1 and rest of the network to go through fa0/0. What can I do to make this possible?
I know how to set Local Preference on an interface... but then all networks will take that specific path.
route-map LP_FA0/1 permit 10 set local-preference 200 neighbor 192.168.2.1 route-map LP_FA0/1 in

Lately I've been experiencing connection problems between my router and cable modem. Every night after 11:00 PM EST, my Internet connection sporadically goes out. I called my ISP who said there was nothing wrong on their end. Plugging directly into my modem allows me to access the Internet. When I wake up in the morning, the connection is back until 11 or later again. I ran WireShark but I'm not sure what to be looking for. There are a lot of random things from the LLMNR protocol like standard query A zmtvrjaql.

I have a 5540, and i am trying to allow access to internet for an specific network object group, who has inside a bunch of users, who needs direct internet access without any restrictions, i have tried with dynamic NAT, but that configuration ask for a specific IP o a Network range, and is not permitted to configure an object group as a source
The group is located in LAN zone, so a permission from one zone to another zone is needed i think, but i can allow the internet acess to that group Is there another way to get that , different from NAT ?

I have a WS-C3750G-24T-S layer 3 switch and I need to configure independent routes for a specific network, I'm trying to use VRF but it is not working for me. I tried using route-map but it seems the switch doesn't support that, so I'm stuck with VRF, but I think I'm not doing it right. The topology is as follows:
I have a network directly connected to a vlan and I need to forward all the traffic I get on this VLAN using a tunnel to a router. I think the problem is that in order to use the tunnel I need to utilize another VLAN which isn't part of that VRF. I attach the configuration I'm using to better understand what I'm trying to do:
layer-3 switch:
ip vrf TEST
rd 1:1
interface Tunnel1
ip vrf forwarding TEST
ip address 172.17.0.1 255.255.255.252
tunnel source 10.245.0.9
tunnel destination 10.250.4.31
[Code]....
And this is how my routing table looks on this router:
172.17.0.0/30 is subnetted, 1 subnets
C 172.17.0.0 is directly connected, Tunnel4
C 10.250.4.0/24 is directly connected, Vlan404
S 10.245.0.8/29 [1/0] via 10.250.4.1
S* 0.0.0.0/0 [1/0] via 10.1.60.15

This past weekend I went out of town and took my Windows 7 laptop with me -- since I returned home, it has been unable to connect to my wireless network. Other devices in my home connect to the network just fine, and the problem laptop has always been fine until now. My network card is an Atheros AR9285, and I'm attempting to connect to a Medialink router with WPA password protection and AES encryption.My wireless network icon in the task bar has a yellow sign with an exclamation point in it. It says "No Internet access."
